Abstract: Systems and methods are configured to synchronize a medical device intervention wherein the anatomy moves or changes shape relative to the medical device. A medical device is positioned relative to anatomy. Data is then obtained regarding a position of the anatomy. The data is used to synchronize a position of the medical device relative to the anatomy such as to maintain a relative position between the medical device and the anatomy such as a specific portion of the anatomy.

Abstract: A cannula and catheter system includes a cannula or catheter formed of an elongated body having a central lumen. The catheter has an outer sheath of rigid material. An inner tube is co-axially positioned within the outer sheath wherein the inner tube is made of a material that is less stiff than the outer sheath or wherein the outer sheath is more stiff or rigid than one or more sheaths, tubes or cannulas slidably nested within the outer sheath.

Abstract: A pick head system includes a pick head having a tip through which a vacuum-assisted force can be applied to pick up an object at the tip of the pick head. The pick head has an internal lumen that forms a tip opening at the tip of the pick head. A housing of the pick head has an internal shaft in which the pick head is positioned. The system can be actuated to achieve relative movement between the pick head and the housing and transition the pick head between a retracted state that applies the vacuum-assisted force for picking up an object and an extended state that interrupts the vacuum-assisted force to release the object.

Abstract: A therapeutic delivery system includes a cannula configured to deliver a therapeutic into an anatomical region, the cannula having an internal lumen and a pumping system coupled to the cannula. The pumping system is inline of a therapeutic flow pathway between a therapeutic source and the cannula. The pumping system is configured to drive the therapeutic from the therapeutic source and toward the cannula.

Abstract: A system for determining gas characteristics at high altitudes in embodiments of the present invention may have one or more of the following features: (a) a high-altitude balloon having one or more of the following features: (a) a balloon, (b) a balloonsat operably coupled to the balloon, (c) an air path chamber wherein gas at a high altitude can occupy the air path chamber, (d) a first speaker located on a substrate within the air path chamber, wherein the first speaker takes an electrical signal input and creates a first sound wave, and (e) a second speaker located on the substrate facing opposite of the first speaker located outside of the air path chamber, wherein the second speaker takes the electrical signal and creates a second sound wave.

Abstract: There is disclosed a multi-player game system for allowing a user to play a repeatable game of chance in a competitive context against at least one competitor, the game system comprising: a client device (410) operable by the user, providing a user interface module which is configured to display the state of a game of chance played by the user and to receive user input requesting a new result of the game of chance; a game engine (430, 432, 434), configured to provide a new result of the game of chance to the client device on receipt of a request from the client device (410) to provide the new result, where the system further comprises a multi-player engine (440), configured to: process multi-player game data representing a multi-player game that links a plurality of games of chance being played by a respective plurality of players on a respective plurality of client devices, said plurality of players consisting of said user and at least one competitor, and transmit to the client device (410) state data relati
